Specification of Letters Patent.

Patented Feb. 13, 1906.

To all whom it may concern:

Be it known that we,ALBERT ERNEST IVE- soN, manufacturer, residing at The Hollies, Gainsborough, in the county of Lincoln, and ARCHIBALD RALPH WVILsoN, chemist, residing at Silverlea, Portland Villas, Hove, Brighton, in the county of Sussex, England, subjects of the King of Great Britain, have invented certain new and useful Improvements in Comminuting-Machines, of which the following is a specification.

This invention relates to segregating machines or apparatus for pressing, dividing, and cutting up pulpy or plastic material, such as food substances, or for the like purposes, and while same will be found specially applicable for use in the preparation of food substances in a granular or finely-divided form either for human use or for feeding animals, poultry, game, &c., yet said machine or apparatus may be employed for any other purpose or purposes to which same is or may be applicable, but is preferably used in the preparation of suet. For example, the machine or apparatus according to the present invention may be employed in carryingout the processes set forth in our British Patent No. 9,148 of 1903 or Ivesons British Patent No. 24,849 of 1901 and Ivesons United States Patent No. 716,235, dated December 16, 1902. In the specification and drawings of Ivesons British Patent No. 24,850 of 1901 there is described and illustrated a machine or apparatus in which the piston or plunger operates in a cylinder or compression-chamber, the end of which latter is closed by or provided with a die or perforated plate or cylinder end having a series of holes or apertures, tubes, or nipples or equivalent therein; and part of the present invention has for its object improvements in such machines or analogous apparatus as follows:

In the accompanying drawings we have illustrated (by way of example) a quaduple machine'i. 6., a machine having two pairs of compression cylinders or chambersar ranged and mounted and operated in accordance with the present invention.

Referring to the accompanying drawings, in which like references denote like parts, Figure 1 is a side elevation of such a machine. Fig. 2 is a plan, partly in section. Fig. 3 is a sectional end elevation. Fig. 4 is a modification of the construction shown in Fig. 1.

Fig. 5 is a plan of Fig. 4 looking up from beneath.

A A are the compressing cylinders or chambers. A A are the plungers mounted on the screwed piston-rods A A engaging with and operated by the internally-threaded sleeves A A which are secured to the gear-wheels A A. A is a feather fixed to the framework, on which feather the groove A in the screw A travels to prevent rotation of the.

. back to back the two bevel-wheels B B B is the bevel-wheel meshing with B and carrying and operating the cutter B.

D is the belt-pulley common to the backto-back bevel-wheels B B. D is the belt driving same.

D is the driving-pulley mounted on the outside driven shaft D E is the collar-ring supporting perforated bottom plate B and screwed onto the cylinder A.

E is the loose ring screwed to E. E is the ball-race formed on said ring E. E E are the balls running in said race.

F is the double-faced cone-clutch sliding on a feather on the shaft G.

F and F are two pulleys running loose on the shaft G and capable of engaging with the clutch F.

F and F are two opposite-direction-running belts imparting power from outside the machine to the loose pulleys F and F G is the main shaft, upon which the clutch F and the pulleys F and F are mounted.

G and G are a pair of bevel-wheels imparting motion from the shaft G to the vertical shaft G and so on to the threaded pistonsleeves A A by means of the train of wheels G G H is one of the cross-heads placed across the upward path of the screwed piston-rods. H and H are the vertical rods attached to same.

H is one of the counterweights.

H is a stop for cylinder to rest against when. in its vertical position.

H is the rod-coupling the cross-head H to the bell-crank H J is one of the vertical rods placed in the path of travel of the piston-rods.

J is the bell-crank operated by the rod J.

J is the spring-joint between the bellcrank J and the slidin rod J J and J are the be t-forks, and J and J are oppositely-running belts driven from any suitable source of power, advantageously from the same source as the belts F F.

K, K, K and K are two fast and two loose pulleys driven by the opposite-direction-running belts J 6 and J.

K is a screw-threaded sleeve on which the respective fast pulleys of the two aforesaid pairs of pulleys are fixed.

K is the screwed end of the slide-rod K K dis a double-slotted link formed in said slidero K is the lever operating the clutch F by means of a pin-and-slot construction. K is the counterweight on the end of said lever.

The cutter B is operated in any suitable manner so as tobe moved with respect to the aforesaid perforated plate. For instance, said cutter may be reciprocated across the face of said plate or may be revolved with respect to same, and in carrying this part of the invention into practice we have found it advantageous to employ a single cutter, as illustrated, extending across the diameter of the perforated plate and arranged to be revolved close against the exterior face thereof, so that as the material or substance from the inside of the cylinder is squeezed or pressed through the apertures in said cylinder at B the revolving cutter B will out said material off as same is compressed and forced through said perforated plate. In carrying. out this part of the present invention the said cutter B may be rotated by means of a revoluble collar or wheel-namely, the bevel toothed wheel B -adapted to rotate upon and round the cylinder end, and, if desired, the cutter may be mounted on a pin B located in the center of the bottom part of the cylinder and kept pressed up to its work by means of a spring B or otherwise suitably arranged and mounted so that same is kept up to its work, the said cutter B being adapted to be revolved either in actual rubbing contact with the outside face of said perforated plate, as illustrated, or otherwise as desired. The aforesaid bevel toothed wheel or other wheel or collar may be rotated round the cylinder end by any suitable means, such as a belt or.

toothed gear-wheel B The cylinder or compression-chamber and means for pressing the material or substance inside said compression-chamber and forcing out saidmaterial through said perforations may either be of the character set forth in the aforesaid Patent No. 24,850 of 1901 or of any other desired and suitable character.

According to the second part of the present invention we mount a plurality of the compression-chambers A A and plungers A A and advantageously so as to operate in pairs, and any suitable number of'said pairs of compression-chambers may be arranged in each machine, as desired, and for the sake of example we will describe a quadruple machine'i. a, a machine having two pairs of compressionchambers-arranged and mounted and operated according to our present invention, as follows: The four cylinders or compressionchambers A A are mounted in a suitable frame ranged either in alinement or back to back. Each pair of cylinders on their adjoining sides are joined together and on their opposite sides are pivoted at C or otherwise arranged to turn in the frame 0 supporting same. For example, the said pair of cylinders on their adjoining faces at the upper end are connected by a stout plate, while in alinement with the centers on which said pairs of cylinders turn said pairs are joined by a stout pin or shaft G on which latter there are journaled two bevel cog-wheels B B back to back, connected to one another and to a belt-pulley D common to both located between same, each said bevel-wheel, respectively, gearing with a bevel gear-wheel B or collar carrying and operating the aforesaid cutter B, which is thereby revolved with respect to the perforated cylinder end B, or the perforated plate may be mounted on the cylinder end and the cutter mounted and operated as follows: The perforated plate B is held and locked in position on the cylinder end by means of a collar E of varying diameters, part of which collar is internally screw-threaded and adapted to be screwed on the cylinder end, while said collar is also provided with a shoulder adapted to fit flush against the bottom end of the cylinder and the second shoulder or rabbet adapted to receive and fit over the said perforated plate, and thereby lock and hold the same firmly against the cylinderbody, while round the exterior of said collar same is adapted to receive and form a bearing in which revolves the bevel gear-wheel B, which actuates the cutter B, a ring E being screwed onto the exterior of said collar E to hold said bevel gear-wheel in position, and a ball-race E is advantageously provided with balls E therein, so that said bevel gearwheel can revolve on ball-bearings round the collar, the cutter B consisting of a single plate or arm extending right across the diameter of the perforated plate forming the cylinder end, this arm being arranged to revolve round a central pin B provided in the said perforated plate, and motion from the revolving bevel gear-wheel B is conveyed to -C C, said two pairs of cylinders being arsaid cutter through the medium of two or other suitable number of arms 13 B which are fixed to the revolving bevel gear-wheels B and to the aforesaid cutter, respectively, these arms being advantageously springarms so constructed and connected to the cutter as to be adapted to keep the latter pressed up to its work, while at the same time revolving said cutter in a positive manner. The said belt-pulley D, located between said pair of bevel-wheels, may either be continuously operated by any suitable belt or same may be operated only during the descent of the plungers A A-that is, only while the compression and expulsion of the material from the compression-chamber A is taking place-and on the return stroke of the plungers the rotation of said bevelwheels B B may be automatically cut? off and restarted when the descent of the plungers takes place, and so on. For example, said belt-pulley, located between said pair of bevel-wheels, may be driven in one direction only-namely, by a belt D from a drivingpulley D on a shaft D which driving-pulley is mounted on said shaft so as to be rotated by and with the shaft when the shaft is revolved in one direction, while when the shaft is revolved in the opposite direction said driving-pulley will be left idle or free, any suitable mechanism being employed for this purpose, such as a pawl-and-ratchet clutch arrangement or any of the well-known freewheel devices as employed in the propulsion of cycles, provided same are suitable for our purposenamely, to drive said driving-pulley in one direction and to leave it free in the opposite direction, the shaft D on which this driving-pulley is mounted, being operated first in one direction and then in the other by suitable intermediate mechanism from the main clutch, by which each pair of plungers and cylinders in turn are operated, such clutch being of any suitable character adapted to automatically operate so that the shaft mechanism driven by said clutch is alternately driven in one direction and then in the other, and thereby each pair of cylinders and plungers are alternately operated. For example, we may employ a right and left handed cone-clutch F, adapted to move into engagement with either of two pulleys F F located on opposite sides thereof and driven in opposite directions, whereby motion from either one or the other of said pulleys (which in turn are driven by belts F F from the main power-shaft or by any other suitable means) is imparted through said double coneclutch sliding on a feather to the main shaft G, from which latter and suitable intermediate gear, such as bevel-wheels G G and a vertical shaft G thereby motion is imparted to a train of toothed wheels Gr G one of which meshes with one of a train of gearwheels which are fixed or formed on the rotary sleeves A which are internally screwthreaded and through which pass the screwed piston-rods A which carry the pistons or plungers A, which latter are thereby forced into the cylinders A or drawn out of same alternately. Upon the withdrawal of one pair of pistons the upper end of said pair of screwed pistonrods bear against a cross head or bar H placed in the path of travel of said piston-rods, whereby said cross-head is forcibly lifted as the pistons leave the cylinders, and such cross-head by means of vertical rods H, carried thereby, causes the pair of cylinders to be tilted forward against the action of a heavy counterweight H carried on said pair of pivoted cylinders, while on the reversal of the direction of rotation of the machinery (by the aforesaid clutch) and the consequent descent of said screwed pistonrods thereby the cylinders are forced back or are free to be brought back by the counterweight H untilthey are exactly in vertical alinement under the pistons, when they are brought to rest by any suitable means, such as a stop H, and having in the meantime been charged with the desired material the plungers on now descending into the cylinders act on said material as hereinbefore described. Furthermore, we advantageously connect each said cross-head H to a rod H adapt- 5 ed to operate a bell-crank H pivoted to the lower part of the frame of the machine,which bell-cranks in turn are adapted to operate the double clutch F F, this arrangement being what we term an auxiliary or emer gency clutch-operating gear, so as to insure the clutch being thrown in and out of action at the proper time in case the principal clutch-operating mechanism to be hereinafter described should from any cause fail to act.

The reversing-gear or, as we have just previously termed it, the principal gear for operating the aforesaid double clutch may advantageously be as follows: WVe arrange a vertical rod or arm J in the path of travel of one or both of the pistons in each pair of pistons, this rod being advantageously acted on by the piston-rods A just before the latter come to the end of the outstroke, whereupon, through the medium of said rod J and a bellcrank J, which is spring-jointed at J to a slide-rod J said rod J operates belt-forks J and J to thereby move one of the belts J and J (driven from the power-shaft outside the machine) from a loose pulley to a fast pulley, which latter is fixed on an internallyscrew-threaded sleeve K within which is inserted the screwed end K of a slide-rod K, provided with a double-slotted link or other suitable device K by which latter said sliderod K when moved operates upon a clutchlever K which is advantageously provided with a heavy weight K so as to render same dead-beat when at rest, and which when said clutch-lever is moved from the vertical center will then rapidly throw the clutch F across into engagement to reverse the machine, whereby the pistons are then forced down. The reversing mechanism is released by moving the belt from the fast back to the loose pulley, and the descent of said pair of pistons continues while the other pair are now being withdrawn, and these latter in turn operate corresponding reversing devices, bell-crank J, spring J and belt-forks J with intermediate rod J connecting same, whereby an oppositely-driven belt J from the power shaft outside the machine is moved from its idle pulley onto a fast pulley fixed also on the aforesaid internally-screwthreaded sleeve K, which latter is consequently revolved in the opposite direction and causes the screw K in same to move the clutch-lever K and thereby throw the clutch F over and drive the machine in the opposite direction, and so on. By this arrangement the reversal of the machine is entirely automatic, and by reason of the emergency or auxiliary reversing mechanism it is practically impossible for an accident to happen in the automatic reversing of the machine.

By reason of the arrangement of the compression-chambers in pairs and arranging said pairs to operate alternately we are thereby enabled to work the machine with less power and attendance. Furthermore, if desired, means may be provided to withdraw the plungers out of the compression-chambers at a greatlyaccelerated speed over that at which they are forced into the compressionchambers, any suitable means being employed for this quickened return movement.

What we claim is 1. In a comminuting-machine, the combinationof a series of compression-cylinders open at the top, a perforated bottom-plate on each of said cylinders, means for alternately and automatically tilting said cylinders at any desired angle, means for returning said cylinders to their upright position, a series of plungers adapted to fit into and be entirely withdrawn from the open end of their corresponding cylinders, and cutting means adapted to move in contact with the outside face of each of said perforated bottom-plates, substantially as shown and described.
